.Still another obj ect of the invention 1s the `production-of an-oil burner, embodying improved jet. .which may .be .readily taken apart andi assembled cleaning. f AFurthermore, the invention' contemplates an -oil burner having ajet provided with' an adjustable opening. IVith these and other objects in View the invention will be clearly understood from the following description, reference being had to vthe accompanying drawings( `of, which: f y., ,y v Fig. l isan elevation of a device,;con structed vin accordance with the invention, parts being cutaway and shown in section, and .i. 2"'

Fig. 2 isa plan ofthe adjustable jet cap.

Referring to the illustration, 1 represents a suitable generating pan, adaptedto be supported by the usual furnace grates, or otherwise. Above the said pan is mounted a U-shaped duct, comprising arms, 2'and 3, and a web, 4, interconnecting the lower ends of the arms. From the arm, 2, adjacent the web, 4, depends an induction tube, 5, which may be formed integrally with the U-shaped duct and is kadapted to communicate with a suitable source of oil supply. The upper ends of the arms, 2 and 3, are interconnected by, and communicate with, an enlarged chamber, 6, in which the oil is vaporized and expanded.

The web, 4, is provided with a vertical, transverse opening, 7, through which projects a cylindrical nozzle, 8, threaded into the opening, 7, as at 9,.and projecting a distance therethrough, and having on its lower end a shoulder, 10, betweenwhich and the web, 4:, may be interposed packing, 13.
